New cave system discovered in Matlock! Overnight a new cave system was discovered under Smedley Street , Matlock. Severn Trent Swallet has a large entrance but it is a little tight beyond. A leader system is in place to protect the unusual formations.So if you want to visit please contact Mr Itsa Gusher, of the Severn Trent Open Pipe Surgery team.

Needs a gate .

It's gonna be sealed for conservation reasons  :tease:

Dye-tracing should be easy enough though. Are we near the Upper or Lower Lava?

Probably on the shale-limestone boundary there, Phil!
